This selects the native threads implementation for the selected
system and C library.
For example, on Linux with glibc, this is NPTL; on Windows with
mingw, this is win32.

Create /etc/ld.so.conf file in the sysroot directory for the
target.
Note that Buildroot errors out if it sees /etc/ld.so.conf.

string "Extra directories to add to /etc/ld.so.conf"
depends on CREATE_LDSO_CONF
help
Extra directories to include in /etc/ld.so.conf. The directories
will be augmented per compiler's multilib specification,
if applicable. For example, if the compiler's multilibs include
/lib and /lib64, and you specify /usr/local/lib here, ld.so.conf
will have both /usr/local/lib and /usr/local/lib64.
config LIBC_XLDD
bool
prompt "Install a cross ldd-like helper"
depends on SHARED_LIBS
depends on ! BARE_METAL
default y
help
Say 'Y' here if you want to have a ldd-like helper that
you can run on your build system, and that will (try to)
resolve shared libraries dependencies as if run on the
target.
Note that the cross-ldd helper is not a full replacement
for the native ldd. Please see the help, by running it
with '--help' for more explanations.
